deep_isin

deep_isin is a Python package that allows you to safely check whether a specific value exists in nested data structures such as dictionaries, lists, tuples, and sets. It also safely handles circular references to prevent infinite recursion.

Installation:

pip install deep_isin

Usage:

Import the entire module:

import deep_isin

data = {123: [1, 2, {456: [7, 8]}], "abc": (9, 10)}

print(deep_isin.isin(data, 7))    # True
print(deep_isin.isin(data, 99))   # False

Import the function directly:

from deep_isin import isin

data = {123: [1, 2, {456: [7, 8]}], "abc": (9, 10)}

print(isin(data, 456))   # True
print(isin(data, 0))     # False

Features:

Works with nested dictionaries, lists, tuples, and sets.
Checks both keys and values in dictionaries.
Handles circular references safely to avoid infinite recursion.
Can handle any mix of nested Python data structures.
